Hi Susie

Bots are effected by the lighting in the region just as your avatar is. You can set up a light script to cover the whole area or just the bot, however...

I've found the lighting script to be very glitchy when you first apply it and you may not be seeing things as others are. The best way is to jump out of the region and back in. F5 doesn't seem to help.


The following was written by Dial_Tone on Wraiths Blog...

Create Lighting

This allows you to set a prop as a light source, by giving the script a unique name.
It creates a tint on the prop of the color(Red,Green,Blue) you set.
You can also set the intensity of the light source (defaults to 100 which is fairly dark. Values higher than 3000 don't seem to make a difference.)

Notes: The main purpose of this script is to create a source of light to be used by the Create Lighting Area (Extended) script, and to make the light source visually obvious by affecting the visual appearance of the prop it is attached to.

Create Lighting Area

This allows you to set an area as a light source, by giving the script a unique name, and to control the lighting within a given area.
This is best used with a Trigger Box prop but any prop can be used.
You can set the overall ambient lighting of the area (in RGB color) which changes how lit props and avatars appear within the region. (props with the Texture Unlit state checked are not affected)
You can also set a directional light source (in RGB color) as well as the direction the light is coming from (X,Y,Z values from -1 to +1). This will in affect cause the directional light appear to come from a specific direction, and light props/avatars accordingly. (ie. an avatar standing in the area may only be lit from one side while the other side is cast in shadow)

Create Lighting Area (Extended)

This allows you to extend the lighting effects from a determined source of light ( as set above).

The only parameter here is the light source name (from either Create Lighting or Create Lighting Area script)
This extends the lighting effects from the light source into the area of this script. The direction of the lighting would then appear to come from the location of the original source.
This is best used with a Trigger Box prop.

Note: Setting two or more props as the same light source (using the same name in more than one script) can have undesirable effects, but can also allow you to create unique lighting effects.

Examples:

Example 1:
Using a Street Lamp prop, add the Create Lighting script, give it a name of "Lamp1", and set the desired RGB color and intensity.
Next, create a Trigger Box prop around the street lamp, add the Create Lighting Area (extended) script, and enter the name "Lamp1".
The area around the steet lamp will now be lit in the color you specified, and the source of the light will appear to come from the street lamp. Regions away from the center of the area will be cast in a shadow.

Example 2:
Using a Trigger Box prop, add the Create Lighting Area script, give it a name of "Source1".
Next set the ambient light level (in RGB color).
Next set the desired directional RGB color.
Next set the direction of the light source (X,Y,Z directions from -1 to +1. A Y setting of -1 means the source shines downward from above, where +1 means it shines upward from below.)
The inside area of this region will have an overall light level and color set by the ambient levels.
Props/Avatars in this region will be lit according to the directional color levels, which the source of the light coming from the direction set by the XYZ values.

Example 3:
Now, create a Trigger Box prop around the prop used in Example 2, add the Create Lighting Area (extended) script, and enter the name "Source1".
The inside area of this region will have an overall light level and color set by the ambient levels from Example 2.
Props/Avatars in this region will be lit according to the directional color levels set in Example 2, with the source of the light coming from the prop used in Example 2.
Regions away from the center of the area will be cast in a slight shadow, depending on the ambient levels from Example 2 (if the ambient light levels are high enough, there will not be a shadow. There will instead be a glow or light cast upon the prop/avatar as if coming from the source in Example 2).

hi one thing I've noticed as I have bots is. If the prop they are created on such as a generic box which I have used alot. If the box is to deep into a collided floor as a zaby it will make the bot darker. Adjusting it up I found solves that issue. A few clicks at a time up or down. Generic box also needs to be made invisible in state tab for a custom bot.

The Bots as any other props are influenced by environmental light, but unlike these, they don't change if the Emissive, Ambient and Diffuse light is set or if Unlight is selected.

To modify the brightness of a bot, whether in our place we have light scripts or we use the default light, we need to insert the prop with the Create Custom Bot script into a further Light Trigger placed in the same coordinates.

To the right of the following picture I show you a bot in a dark place and to the left one realized as I explained above
